Acute and continuation therapy in unipolar depression: observations from the run-in phase of a maintenance trial.

OBJECTIVE

The aim of the study was to analyze treatments and outcome in depressed patients.

METHOD

Patients with recurrent depressive disorder (n = 289), recruited for a prophylaxis study, were followed up in hospital settings for 6 months with diagnostic and depression ratings at baseline and monthly depression ratings. Data on psychotropic drugs were retrieved from hospital case records. Independent associations between baseline, treatment and outcome variables were examined by logistic regression models.

RESULTS

Depressive symptoms subsided gradually. After 6 months, 21% had dropped out, 43% were rated as remitted (HAM-D-17 <8) and 8% had not responded (HAM-D-17 >15). Patients once remitted rarely relapsed (<5%). All patients received antidepressant drugs, half of them more than one (2-4) as well as other psychotropic drugs. Patients responding poorly received more frequently multiple antidepressants, tricyclic antidepressants, hypnosedatives, lithium and/or antipsychotics.

CONCLUSION

The 6-month outcome was generally poor. Choice of treatment appeared at least partly to be determined by the therapeutic outcome.
